How much hydrogen chloride acid was used?

72.916 g of hydrochloric acid was used.

Given:

Mass of Zn = 65.39 g

Mass of ZnCl_{2} =136.29 g

Mass of H_{2} = 2 g

Equation:

The chemical equation for the reaction of zinc with hydrochloric acid:

Zn + 2HCl → Zn Cl_{2} + H_{2}

Hydrogen gas is created when zinc combines with hydrochloric acid, which causes the process to bubble ferociously. Another sign that a chemical reaction is taking place is the generation of a gas.

Calculation:

A number of equivalents equate:

Number of equivalents = \frac{given mass}{Molecular Mass} x 1000 x equivalent factor

\frac{x}{36.458} x 1000 x 1 = \frac{136.29}{136.286} x 1000 x 2

x = 36.458 x 2

x = 72.916

Firdavs [7]

Answer: V2 = 35.54L

Explanation:

Applying

P1= 67.4, V1= 85, T1= 245, P2= 179.6, V2= ?,. T2=273

P1V1/ T1= P2V2/T2

Substitute and simplify

(67.4*85)/245 = (179.6*V2)/273

V2= 35.54L
